amps for the horns (BD-Design)

For a decade or so I used single ended triode amps, Cary Audio 2a3, mono blocks on the Oris 150/AER MD3 and Fostex t900a bullet tweeters of my three way all horn loaded systems. Then I listened to one of Mr. Nelson Pass' First Watt F3 Jfet artisan stereo power amps. The F3s output 10 watts into a 16 ohm load and 15 watts into a 8 ohm load. As I understand it the single gain stage F3 is a single ended class A circuit. At any rate I loved the warm, rich, realistically textured, natural and immediate sound of these solid state amplifiers. I sold the 2a3 mono blocks. I now use a pair of First Watt F3 stereo solid state amps on the Oris 150 and Fostex bullet tweeters. My stereo system sounds better than it ever has before.
